JOHN H. KINEALY, OF FERGUSON, MISSOURI PUMP DEVICE.

To all whom it may concern:

Be it known that I, JOHN H. KINEALY, a citizen of the United States, residing at Ferguson, in the county of St. Louis and the State of Missouri, have invented a new and useful Improvement in Pump Devices, of which the following is a full, clear, and exact specification, reference being had to the accompanying drawings, which form a part thereof.

devices in which the fluid to be pumped is induced to flow into the device by a vacuum produced therein by the condensation of steam and the fluid to be pumped is made to flow out of and away from the device by the introduction therein of steam.

My invention relates especially to pump devices used in connection with heating systems for the purpose of withdrawing the air from said systems so as to make it easier for the steam to circulate through the various parts of said heating systems, and also to enable the steam to be circulated through said systems at a pressure less than that of the atmosphere.

The object of my invention is to provide will be easily deranged or that will require any especial care or attention, and a device which may be operated with steam at a low pressure.

My invention is fully shown in the accompanying drawings where similar letters are used to designate similar parts.

Figure 1 is a view showing the device partly in elevation and partly in section and connected to the air line of a heating system; Fig. 2 is a vertical sectional view of Fig. 1 along the line 2-2; and Fig. 3 is a vertical sectional view of Fig. 2 along the line 3-3.

Referring to the figures, A is a closed tank forming a primary vessel; and B and C are parts of a secondary vessel connected to the vessel A by means of the nipple D which extends, preferably, from the upper part of the box G to the upper part of the vessel A.

C is the top of the box or upper part .C of the secondary vessel. 7

E is a steam pipe through which steam is conveyed from a suitable source of supply of the box C through the steam valve Q, and F is a water pipe through which water is conveyed from a suitable source of sup ply to the box C through the valve 1 Specification of Letters Patent.

G is an air pipe which is connected at one end to the heating system and at the other end to the tank A, preferably near the bottom thereof, and which serves as a suction pipe for the device. This pipe G is provided with a valve G and a check valve K which latter is adapted to allow the passage .therethrough of any fluid into the tank A i but to prevent the passage therethrough of any fluid from the tank A.

My invention relates to that class of pump f H is a discharge pipe connected to the leg B of the secondary vessel. The pipe H is preferably connected into the bottom of the leg B as shown in the drawing and is provided wlt-h a siphon conslsting of two vertical legs M and N.

I is a check valve adapted to allow the passage of a fluid from the leg B but to prevent the passage of a fluid into the leg B.

L is a discharge pipe which is provided with a check valve J adapted to allow the ,passage of a fluidfrom the tank A but to prevent the passage of a fluid into the tank A. The discharge pipe L is provided with a vertical branch 0 open at its upper end and adapted to receive water discharged 1 from the-leg N of the pipe H. a device that will comprise no parts that I The steam valve Q and the water valve P are similar in construction andeach comprises a body part whereby it is attached by a threaded projection to the side of the box C; and each has inside of it a seat g and 79', respectively, in which are openings 90; and each of these valves has a valve piece Q and 79, respectively, which is provided with perforations 02 adapted to register with the perforations a" in the seats g and 39, respectively, when the valves g and p are open. The valve pieces Q and are adapt- .ed to rotate or turn in contact with the seats 9 and 29, respectively.

It and h are valve stems of the valves Q and P, respectively, which are attached to the valve pieces and p and which rotate in and are supported by the tubular braces 70 and 72, respectively. These braces, 70 and 70, project inside of the box 0, and the brace 70 of the water valve P is threaded on that part which projects inside of the box C land carries a nut Z having a beveled inner part Z which may be screwed up close to the inner end of the opening through the valve around the brace, so that when water passes though the valve it is made to enter the box in the form of spray or a finely divided mist.

0' is an overweight mounted on the triprod 9 which is attached to the pin a shaft- 6.

The pins (l and c are both adapted 'to' move-inbearings in the supports 1* which are carried by the brackets t'w'hich project inward-1y from the sidesof the box C. Mountedo'nthe upper ends of the pin 6 are 'U- trips 'o'and "0 which engage with the arms m and'm, respectively, fastened to the valve stems h and h respectively.

The rod 'f'has attached to it two arms to and '10 adapted to engage with and move the trip-rod g.

8 represents set screws by which the U- trips and thearms m and m are held in place. 7

' u is a bucket suspended from the float a by means of the *link 22, and whose outside diameter is nearly the same as the inside diameter of the leg '13. The weightof the box 0' and the leg B is carried partly by the nipple D and partly by thesu pport X.

The "operationof the pump is as follows: When the valve mechanism is in the position shown in Fig. 1 the water valve P is open and water 'passes from the pipe F into the box (lfrom where it passes down into the'leg 'B. The water continues to flow into the loox u'ntil it has accumulated in the leg B, and the box C," and the pipe H until it has reached a level sufficient to raise the fioa'ta and move the trip-rod 9 toward the right just past a vertical position, then the'in'fluence of the overweight 0 is such that instead of opposing the upward movement of the float it falls freely toward the right and carries with it the U-trips 0 and 0 and they contact with the arms 9% and m, re spectively, and cause the valve pieces 9 and p to rotate on their seats, thus closing the water valve 'P and opening the steam valve Q,"as shown in Figs. 2 and 3. Then steam passes from the pipe E into the box C and from there through the nipple D into the closedftank A. As "the steam continues to enter the 'boxG it exerts a slight pressure which is sufficient to depress the water in thebox C so that it overflows the top of the siphon formed by the legs M and N of the pipe H, and then the water begins to flow from the box C and the leg B through the pipe Hinto'the open pipe 0. The water continues to flow until'the level of the water in'the leg B has fallen so that the weight of the water which remains in the bucket a above the level of the water outside of this bucket is sufficient to move the float downward and make the arm w engage with the trip-rod g and cause this rod with the overment through the medium of the U-trips 0 and 0 and the arms in and m, the steam valve Q will be closed and the water valve P will be opened so that steam will cease to flow into the box G and water will begin to flow therein. While the water is being forced out of the box C and the leg B by the pressure of the steam, any air or water that may be in the tank A will be made to pass out therefrom through the check valve J into the discharge pipe L. As soon as the steam valve Q is closed and the water valve P is opened the water entering the box C comes in contact with the steam in the upper part thereof and this steam is condensed and falls with the water to the bottom of the box and into the leg B. As fast as the steam is condensed in the box C steam is drawn from the tank A through the nipple D into the box C and is there condensed so that a vacuum is formed in the tank A and in the box C and the upper part of the leg B. "And while this vacuum is being formed and maintained air is prevented from entering the leg B through the pipe H by the check valve 1, and air is also prevented from entering the vessel. A from the discharge pipe L by the check valve .l, but since the check valve K is adapted to open inwardly toward the vessel air passes from the heating system through the air pipe G, which serves as a suction pipe for the apparatus, into the vessel A. Air continues to pass into the primary vessel A as long'as a vacuum is maintained there by reason of the condensation of the steam in the box C ofthe secondary vessel, and when water has accumulated in the leg B and the box C in suflicient quantity to again raise the float a so as to throw the trip-rod from the position shown by the full lines in Fig. 1 to that indicated by the dotted lines in the same figure or to that indicated in Figs. 2 and 3, then the water valve 1. will be closed and the steam valve Q will be opened and steam will enter the ap 'iaratus and force the water out of the box C and the leg B while also forcing air and any water that may have come with the air, out of the vessel A through the check valve J into the discharge pipe L. The tank A constitutes what may be termed a suction chamber or primary vessel while the box C with the box G to operate the valve mechanism so' as to close the water valve P and open the steam valve E, the vessel A may be completely filled with air or other fluids, and if the resistance to the flow of water from the secondary vessel through the pipe H be such that the Water flows therefrom quite slowly, then steam will continue to enter the box C and the vessel A for quite a long time and everything in the tank A may be forced therefrom through the check valve J and some steam even may pass out through the check valve J and be wasted.

It is advisable to have the discharge pipe H provided with a siphon as shown so that when the apparatus is started for the first time and while cold, sutficient water will accumulate in the secondary vessel to operate the valve mechanism before the water begins to flow through the opening end of the leg N. The top of the siphon formed by the legs M and N should preferably be somewhat above the point of highest level of the water in the box C, and the lower end of the log N should preferably be somewhat above the point of lowest level of the Water in the leg 13.
